They are in the sports card slabbing business. They will do the packaging for you if you tell them the grade and the name you want on the slab. Or they will grade and seal the slab for you. Apparently they are doing business as Grading & Authentication.
They must be OK as they say in their advertising:
Doesn't look like they know anything at all about casino chips (or collectible grading in general).
